A comprehensive rationally-based method is presented for the automated optimum structural design of ships. The method contains three principal features:--a rapid, design-oriented finite element program developed especially for structural optimization;--a comprehensive set of subroutines for the accurate estimation of the various modes of collapse and unserviceability;--an optimization method based on a new form of sequential linearization capable of solving the resulting large-scale, non-linear, highly constrained optimization problem. The objective may be any continuous non-linear function of the design variables, such as weight or cost. The method is illustrated by applying it to the optimal design of a typical general cargo ship. The overall dimensions and the design loads are the same as for SD14. Also, since this vessel has proven to be a successful and cost-effective design, it was used as the basis for determining the load factors and cost ratios for the sample problem. The program contains 74 design variables and 542 constraints, of which 220 are non-linear. Order from BSRA as No. 53,346.
